A Portal Administrator can also delete an entire community. You should never delete a community using the ACC; instead, use the Portal Administration. To delete a community:
Open the Communities tab in the Portal Administration and click the delete link for the community.
A confirmation message appears, warning “Are you sure you want to delete the community <
name>? Deleting this community will also delete any of this community’s shared gears from other communities.” Click on the Yes button to delete the community and all its pages.
Deleted communities will appear as nulls in the userCommunities property of a user profile in the ACC.
